Ex-Cloud9 player of Counter-Strike: Global Offensive Kory Friesen admitted to competing under the influence of Adderall during tournaments, which has forced ESL to make some changes to their policies and adject the rules of their e-sports tournaments.

Talking to Wired Anna Rozwandowicz, head of communications at ESL said “The integrity of our sport is and always will be our biggest concern… We have worked on changes in our rules, reached out to authorities for support, and will be ready to announce our next steps in a couple of days. When that comes out, you can treat that as our full statement on the issue.”

While the incident in question with Friesen took place long enough ago that it’s impossible for the ESL to prove it, it was not the cause of his removal from the team having been let go down to poor performance.

“We have no way of knowing whether he is telling the truth, or just being upset about being removed from the team and trying to annoy them,” Rozwandowicz said. “We’ve had cases of players admitting to cheating, but then denying everything once they found out they can get disqualified and banned for it. Upon investigating, it became clear that the games were played according to the requirements and were protected by anti-cheat software, so no cheating was possible.”

Truth or not, the confession has made the ESL sit up and take notice of their policies regarding drug use (while it is banned there is currently no list of repercussions). A process is now being set up with a governing body and an appeal system – just like a regular sport would have. Drug testing is still a long way off Rozwandowicz says, but they hope that this is a step in the right direction.
